Question

When a ball is thrown straight up with no air resistance, the acceleration at its highest point. A) is upward B) is downward C) is zero D) reverses from upward to downward E) reverses from downward to upward

Answer 1

Answer:

B) is downward

Explanation:

The acceleration is always downward, because it is the gravitational acceleration.

When the ball is going up the acceleration is opposing the movement, and when the ball is going down the velocity has the same direction as the acceleration
